Provider migration

Migrate from OpenAPI Generator to Bloom

OpenAPI Generator is flexible and free, but many teams end up maintaining template forks, custom scripts, and SDK patches by hand.

Checks

What to check

Custom templates need an inventory before replacement.

Generated SDK surface area may change dramatically.

Build scripts and package metadata need migration checks.

Hosted docs and launch reports usually need separate infrastructure.

Checks

Migration checklist

Export source docs, OpenAPI files, theme settings, redirects, and custom domains.

Decide which content remains hand-authored and which references are generated.

Generate a preview before touching production DNS.

Run SDK and docs checks before publishing packages or indexing new pages.

Details

Why Bloom fits

Bloom is OpenAPI-first.

The migration report shows the SDK, docs, and launch work before anything goes live.

SDKs, docs preview, sitemap, and llms.txt live in the same workflow.

The dashboard shows what is generated, ready, and waiting on review.
